What is Seed?

Also known as: germ (of a seed)

Definition 9.1 Primary & Middle School Biology · Chapter 9 — From Seed to Plant

A seed is the beginning of a new plant, made by the parent plant. Inside its protective coat, a seed holds:

  • a tiny plant already started — the germ of the plant, with the beginnings of a root and a shoot;
  • a store of food to feed it until it can feed itself.
Inside the soaked, opened bean: a tiny plant — root tip and folded first leaves — lying against its food store.

Examples

Example 9.2 (Opening a soaked bean)

Soak a big white bean overnight, and its coat slips off easily. The bean opens into two thick halves — the food store — and there, nestled at one edge, lies a tiny pale plant, root tip and folded first leaves, small as a grain of rice. The new plant was there all along.

Example 9.6 (Why sowing waits for spring)

Gardeners sow beans in spring, not in winter: the seed in cold earth would wait — or rot — instead of germinating. Warm days and watered soil are exactly the two signals of Proposition 9.5.

Example 9.10 (One bean, one summer)

Sown in May, a bean germinates in a week; by June it is a leafy plant climbing its pole; in July come white flowers, then green pods; in August the pods hang heavy, each holding a row of new beans — next year’s seeds, made by this year’s plant.
